COMBINATION CARBONA'I'OR AND FILLER.

Specificationof Letters Patent.

Application filed March 20, 1919. Serial No. 283,883.

To all whom it may concern Be it known that we, ELI E. SAGER and OSCAR L. KING, both citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Combination Carbonators and Fillers, of which the following is a specification. This invention relates to a combinatlon carbonator and filler and particularly to means for insuring a thorough mixing of the carbonic acid gas with the liquid to be charged. 4

One ofthe objects of the present invention is to provide a simple, substantial and eas ly operated apparatus for carbonating and (11S- pensing various liquid refreshments such as arecommonly sold over the soda fountain counters today, and particularly an apparatus which permits charging and dispensing of comparatively small quantities of the same.

Another object of the invention is to provide means for insuring a thorough mixing of the gas and the liquid, both during the charging and the dispensing operation.

Further objects will hereinafter appear.

The invention consists of the parts and the construction, combination 'and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1- is a central vertical section through the carbonator and filler.

Fig. 2 is a vertical cross section on line 22 of Fig. 1.

Fig. 3 is a detail section on line 3-3, Fig. 1.

Fig. 4: is a plan view of one of the perfo rated disks employed in the secondary mixin chambers. I

Tteferring to the drawings in detail, A indicates a tank or receiver, in this instance consisting of a cylinder 2, a head member 3 and a bottom member at, the cylinder proper being constructed of glass, or other suitable material while the head and bottom member inclosing' the same may be constructed of any other suitable material and secured by means of stay bolts 5. Both the head and thebottom member are provided with annular grooves as seen at 6 and nozzle 11. These nozzles are ciroumferelr.

tially perforated and these perforations are arranged on an angle, as shown at 12, see Fig. 3, to produce a swirling action when the liquld- 1s discharging, as will hereinafter be described. Extending through the bottom member 4 and centrally positioned be tween the discharge nozzles 11, is an inlet pipe 13, through which the liquid to be charged is admitted. This pipe is provided with a perforated cap 1 1 at its lower end, and

with a regulating valve 15 at its lower end,

the liquid to be charged being preferably admitted from a suitable source under pressure, by means of a pipe 16. Also extend ing through the bottom member at is a charg- Patented (lot. 25, 1921,

ing nozzle 17 and a snifter pipe 18. The I nozzle '17 is perforated laterally at its upper end, as at 19, to permit an even distribution of the gas when admitted and it is also provided with a valve 20 which regulates the admission of gas, as will hereinafter be described. The snifter pipe 18 extends to the upper end of the chamber and regulates the quantity of liquid admitted. This pipe is also provided with a control ing valve shown at 21, which is closed during the charging operation and also while the liquid is being dispensed.

Connected with the discharge passages 9 and 10 are a pair of secondary mixing memhers generally indicated at 22 and as they are both similar in construction, only one will be described. The secondary mixing member consists of a cylinder in which is placed a series of perforated disks 23. These disks are in spaced relation to each other and each disk is provided with a series ofperforations disposed on an angle to the plane in which the plates reside and arranged in circle formation, as shown in Fig. 4. Liquid passing through each disk will discharge in the direction of inclination of the,perforations thereof, and since the perforations are arranged in circular formation the resultant flow of the issuing liquid will be circular until reversed. by passing through the reversely inclined perforations of the next superposed disk. Therefore, a swirling movement is created first in one direction, and then in the opposite direction as the liquid passes upwardly through the secondary mixing chamber, thus insuring a thorough mixing of the gas and liquid before it can discharge and at the time that it is dis charged. The secondary mixing member shown on the left-hand side of Fig. 1 on the drawings is employed for the purpose of charging siphon bottles. It is therefore provided with an attachment such as shown at 24, which permits insertion of the siphon spout. It is also provided with a needle valve 25 by which the flow from the tank *or receiver A may be controlled. That is,

if it is desired to charge or re-fill a siphon bottle, it is accomplished .by first inserting the spout, as shown at 26. The valve on the siphon bottle is then opened and, secondly, the valve 25. The liquid under high pressure contained within the receiver A will then pass through nozzle 11, the passage 9 and the perforated disks 23 and will finally pass by the needle valve 25 directly into the spout of the siphon bottle and will thus enter and fill the bottle. The moment the filling operation has been completed, it will only be necessary to close the needle valve 25 and remove the siphon bottle as a whole, it being obvious that the valve on the siphon bottle is first closed to prevent the escape of liquid under pressure.

The secondary mixer shown on the righthand side of Fig. 1' of the drawings is in this instance employed for filling ordinary bottles or glasses and is therefore connected with a needle valve 28 arranged above the counter; for instance, such as roughly indicated at 29, this valve being used in the manner similar to all dispensers commonly employed at soda fountain counters.

The operation in general will be as follows: Snifter valve 21 is first opened. A liquid to be charged and admitted by'pipe 16 is then permitted to enter the receiver by opening valve 15. This is closed the moment the receiver is completely filled, which is visibly indicated if the cylinder is constructed of glass or otherwise indicated by an overflow through the snifter pipe 18. Valve 21 is closed the moment the filling operation has taken place and it is now only necessary to charge the liquid. This is accomplished by opening valve 20 which is connected with a suitable supply of carbonic acid gas such as is usually received in seamless steel bottles under comparatively high pressure. This bottle may be connected with the valve 20 and the charging nozzle 17 by means of a tube not here shown and a reducing valve regulating the pressure desired, may also be connected on this line but as such arrangements are old in the art and used with practically all forms of charging apparatus employed, it is thought to be unnecessary to further illustrate the same.

The charging of the liquid with carbonic acid gas is therefore accomplished by merely opening the valve 20 and then closing the same the moment the gas flow stops. The device, as a whole, thus filled with a liquid and charged with carbonic acid gas, is ready for use; that is, the liquid may be discharged through valve 28 into glasses or bottles in the usual manner or it may be employed for re-filling ordinary siphon bottles by the connection shown at 24.

From the foregoing description, it can readily be seen that comparatively small quantities of liquidmay be charged for dis pensing service or for re-filling the siphon bottles and that the operation, whether it is re-filling the apparatus or dispensing the liquid receiver, is easily and quickly accomplished. Further, a thorough mixture of the gas and liquid is obtained during the re-filling operation as the gas admitted must pass through the volume of liquid. Again, further mixing of the gas and the liquid is insured when dispensing the liquid as a thorough mixing action-is obtained when the liquid and gas :discharge through the nozzle 11 and the superimposed perforated disks 23.

While a more or less specific arrangementand structure is here shown, we wish it understood that this may be varied and also that the material and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate.

Having thus described our invention, what we claim and desire to secure by Letters Patent is I 1. In a device of the character described, a tank having a base formed with a U-passage establishing communication between the interior and the exterior of the tank, a pipe threaded in the outer end of the U-passage and extending parallel alongside the tank, said pipe'being enlarged above the base to provide a shoulder to seat on the latter, a vertical series of perforated disks arranged in the enlarged portion of the ipe for thoroughly mixing the liquid and gas passing therethrough, and a mixing nozzle secured in the inner end of the U-passage andprovided with lateral tangential inlet ports whereby the liquid and gas entering the nozzle will have a whirling motion imparted thereto.
